Madelyn has x nickels and y dimes, having a maximum of 15 coins worth no
aliina [53]

9514 1404 393

Answer:

 2 nickels, 9 dimes

Step-by-step explanation:

When there are a number of overlapping shaded areas on the graph, I find it convenient to use the reverse of the inequalities. That makes the <em>unshaded</em> area the solution space. Here, the vertices of the triangular solution space are ...

  (2, 9), (2, 13), (6, 9)

Any of the grid points within (or on) this triangle is a possible solution. One of them is (2, 9) corresponding to 2 nickels and 9 dimes.

__

Three solutions are shown:

  (x, y) = (2, 9), (3, 10), (4, 11)

Solve the inequality.<br> 6x + 10 + 10x &lt; 4(4x + 3)
Elena L [17]

Answer:

X = all #'s

why?

6x+10+10x < 4(4x+3)

Combined liked terms

16x + 10 < 16x +12

you can see that there is X on both sides and the lowest one has a +10 and the highest has a +12 so it will always be greater by 2

Let f(x) = x ^ 2 - x - 2 and g(x) = - 6x - 8. Find g(2) and f(g(2)). Mathfrak g (2)= Box (Simplify your answer. ) f(g(2)) = ( Si
jek_recluse [69]

The value of the function f(g) after simplifying and putting 2 in place of <em>x</em> is -20 and the value of f(g(2)) is 418.

<h3>What is composite function?</h3>

When a function is written inside the another function, then such function is called the composite function.

The first function given in the problem is,

f(x) = x^2 - x - 2

The second function given,

g(x) = - 6x - 8

To find out the value of g(2), put the 2 on place of variable x in the above equation as,

g(2) = - 6(2) - 8\\g(2)=-12-8\\g(2)=-20

The composite function f(g(x)) can be given as,

f(g(2))= (-20)^2 - (-20) - 2\\f(g(2))=418

Thus, the value of the function f(g) after simplifying and putting 2 in place of <em>x</em> is -20 and the value of f(g(2)) is 418.

Can someone help me find the value of X I would really appreciate it ;)
ipn [44]

Step-by-step explanation:

the similarity of the triangle:

x/18 = 8/12

=> 12x = 18×8

12x = 144

x = 12
